My invention relates to a heat insulating container whose walls arespaced apart Aby suitable heat insulating material packed in such space,.detachable structure being pro-` vided whereby the inner containerwhich. comprises integral walls may be inserted readily into the outercasing from below when the bottom of the casing isV removed temporarily,and the contents of the inner container in maybe poured out at the topbyconveniently lifting the combined container into dischargingpositionfand removing the stopper, such asa cork or other plug, from,the inner container whose upper end is designed to. ex-V tendabovetheedge of the casing.

It is of especial importance that by properly relating the two spacedparts-the inner container and outer casing, I am enabled to use for .theinner container a receptacle more nearly resembling the usual milkbottle having an enlarged rim adjacentits` opening, from which thecontents may be poured, and to provide `integral with the upper end ofthe outer casing, a pouring lip through which the :contents of thebottle may be delivered.

With my novel construction Iam` able to provide the outer casing withsuch an ,at-c tached handle that the contour of thetwo containerspermits secure support ofthe container as a whole by the handle, and yetsecures the inner container against loosening the same by movementthereof toward the lip end ofthe casing; `and by providing the unit witha detachable base having ,a peripheral {ian-ge, thecasing is supportedin secure vertical position though permitting removal of the innercontainer through the lowerend of the casing. It is an advantage Y,of mycons tructionthat no relative rotation ofthe casing and base is requiredfor .theremoval of the latter.

vIt vis `a further object Aof my invention to provide my outer casingsuitably spaced about the inner container with a heat insulatv ing.packing which may be readily `filled in from the bottom and .packedbetween the receptaclestoward their top ends, and thereafter retainingthe ,packing therein by the same Vbottom part that servesas thebase for1930. seriai No. 446,853.

Other objects andv advantages will be eX-V plained in connection withthe kfollow-ing description of parts, recited in the appended claims andillustrated in the accompanyingv drawing in which,-

plane indicated? My `outer metal casing l and the shorter inner glasscontainer 2 are shown in `the drawing as related V1n my preferred form,as

spaced apart, the latter within the former, Y

and tightly `held in such spaced position by packing in between thecasing and container a heat-insulating filler 8, such as ground corkwhichwill be packed in about the container 2 when the parts arepositioned in inverted arrangement. It will be noted that the 'en largedrim 4L will be crowded upwardly against the reduced inner edge 5 ofthecasing l which thus prevents the packing 3 from escaping outwardly frombetween the parts 1 and 2, whatever the position of the combinedreceptacle.

- It is to be further noted that the casing l hasV an integral body 6 towhich a suitable handle 7 is permanentlyv attached, and yan, annular rimoriiange 8 having outer notch 9 formed beneath the' downwardly-,turnedshoulder 10, is shaped of proper relative size tothe said edge `5 that adownward thrust of the same will `force the rim or flangeS be tween theenlarged rim i and the edge 5 untilV said shoulder 10 rests upon saidedge, and the upper ends of theparts l and 2 aretightly and securelyheld in contiguous position. A portion of said rim -8 is provided withan ,arcV portion l1 'forming a pouring lip 12'f rom which the contentsof the container 2 may be readily and Aeciently poured from the combinedcontainer; i

A The Y`body 6 of the casing l has a ibeadil formed in the integral.casing which serves to. lassist the vertical ,support of. the combinedY container, asidefrom the handle 7 uattaclore-do .i Fig. 1, to tightlyattach thebase-in secured on a particular side of the double container.pouring lip,

This novel feature of bywhich the stopper as a whole may be permitting the inner container to beinserted removed from the bottle within the rim 4, or from below, andastenediin its. upper posireinserted therein as needed. This efhcienttion, is a matter of great value for which stopper 14 is itselfheat-insulating, and the inventor should be protected by Yclaimstherefore Velicient. Y of adequate lscope.
